The solar water heating system is normally installed on the roof of the house and facing south (or north), so that it is exposed to solar radiation all day, avoiding the incidence of shadows. To ensure the proper functioning of the solar water heating system, the installation must be carried out by an expert!
Maintenance for solar water heating system is basic and periodic. It is recommended to clean the tubes evacuated from the solar collector superficially every month, to remove dirt that decreases the thermal efficiency of the equipment. According to the concentration of tartar (or hardness) in the water, it is recommended to drain the thermo tank at least once every 3 months. Changing evacuated tubes is relatively easy to do; however, it is recommended to do so by qualified personnel.
